Answer:
The ordered pair that makes an equation true is called a solution
a)solution
b) not a solution
c) solution
d) solution
e)not a solution
f) not a solution
g) solution
h) not a solution
Step-by-step explanation:
The first number in an ordered pair is x, the second one is y
Plug in the numbers to x and y respectively
I'll give two examples so you know how to solve it
a) y=3x+1
-5=3(-2)+1
make sure you use pemdas (multiply first)
-5=-6+1
add
-5=-5
this is true (meaning it is a solution)
b) 6=3(-3) +1
6=-9+1
6 = -8
this is NOT true (not a solution)
If you have any questions feel free to ask
I'm sorry but the solution you proposed was a bit hard to follow, so I'll just post my solution: we convert "2 and 1/2" to a single fraction:
So, we know that 5/2 gallons cost 60 dollars, which means
To find the cost of a single gallon, we have to solve the equation for g:
Answer:
$11,991.60
Step-by-step explanation:
An appropriate formula is ...
A = P(1 +r/n)^(nt)
where r is the annual rate, n is the number of time per year interest is compounded, and t is the number of year. P is the principal invested.
Filling in the given numbers, we have ...
A = $2000(1 +0.12/12)^(12·15) = $2000(1.01^180) ≈ $11,991.60
The account balance after 15 years will be $11,991.60.
Answer:
A) y=400x+60,000 (really no work needed)
B) 67,200 volumes
C) 50 months after March 2004
Step-by-step explanation:
B) you will find the # of months between march of 2004 and september 2005, which would be 18 months (you exclude march of 2004) and substitute that number in for x in the first equation.
C) Instead of substituting in for x, we will substitute in for Y, so the equation will look like
80,000=400x + 60,000
and you would simplify this by isolating x, meaning that your answer will be 50, so you could say 50 months after march or you could actually find out the date.
